ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an electrical connector for engaging a daughter printed circuit board to a motherboard, and more particularly to an electrical connector which has long, resilient terminals reliably secured in an insulative housing facilitating mating with another electrical connector.
An electrical connector is often required to connect two printed circuit boards together for signal transmission therebetween. For some applications, an electrical connector having a high profile is desired. Therefore, terminals assembled in the connector are required to have a long dimension. One such electrical connector is disclosed in U.S. Pat. No. 5,626,500 (referring to
FIG. 10
) and has a pair of receiving channels
20
and a plurality of terminals
12
. Each terminal
12
consists of a soldering tail
16
, an elongate retention portion
18
and an S-shaped contact
14
. The complicated contacts
14
and the elongate retention portion
18
result in the terminals
12
being unreliably secured in the housing. Furthermore, the terminals of a complementary connector (not shown), if improperly inserted, push into the cupped portions
143
of the ends
142
of the terminals
12
instead of the receiving channels
20
, resulting in an unreliable contact and in a shortened lifespan for the terminal. Additionally, the terminals
12
and the housing with the receiving channels
20
can not be easily manufactured, and the housing is easily damaged. Thus, mass production is problematic.
BRIEF SUMMARY OF THE INVENTION
A main object of the present invention is to provide an electrical connector having a resilient terminal of a long dimension, which can be precisely positioned and reliably secured.
Another object of the present invention is to provide an electrical connector which facilitates mating with another electrical connector and whose manufacture is simplified.
An electrical connector of the present invention comprises an elongate insulative housing, a plurality of rectangular shield plates and a plurality of terminals received in the insulative housing. The insulative housing has a mounting face and a mating face. A pair of receiving channels extends through the insulative housing from the mounting face to the mating face for receiving the terminals, and a plurality of recesses is formed between the receiving channels for receiving the shield plates. Each receiving channel in the insulative housing disposes a plurality of upper ribs and lower ribs for retaining the terminals. Each terminal consists of a contact portion, a retention portion, a transverse portion and a soldering tail. Each retention portion has a first retaining section and a second retaining section. A pair of first locking barbs and a pair of second locking barbs are respectively formed on the first retaining section and the second retaining section of each terminal for fixing the terminal within the insulative housing. The transverse portions are formed between the first retaining sections and the second retaining sections and establish a transverse displacement therebetween for assuring reliable manufacturing and resilience of this long terminal.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
